Optionals
- Soldering Iron with Solder.
- Heat Shrink.
- F-Type Coupler.
- Ferrite Beads.
Personally, I scrapped these off of some digital display cables, they can be found in many places, but are not completely neccessary.
- Copper Terminal Blocks, like these, or these.

The Antenna

The Antenna is a good place to start. Being built is a quad dipole antenna tuned to 137MHz, the approximate frequency of the weather satellites we’re trying to reach.

First, we need to figure out some maths so we can know what we’re cutting, and what we’re putting where, detailed in “Antenna Theory and Mathematics”. TL;DR: 1⁄4 Wavelength of 137 MHz is 54.7 CM.
